GENERAL INFORMATION
4.1.1
GENERAL DESCRIPTION
The KLN 94 is a panel-mounted, long range, GPS based airborne navigation system with a database. The KLN 94 provides VFR, IFR enroute, terminal and non-precision approach functions.
The KLN 94 is certified to TSO C129a.
The primary purpose of the KLN 94 is to provide the pilot with present position information and to
display guidance information with respect to a user defined flight plan. Flight plan information is
entered by the user via various knobs and buttons located on the front panel.
The KLN 94 can use its present position information to determine crosstrack error, distance-towaypoint, ground speed, track angle, time-to-waypoint, bearing-to-waypoint, and advisory VNAV
guidance. The KLN 94 also has instrument approach capabilities.
The KLN 94 can also output some of this information for use by other devices. The internal database of the KLN94 contains information concerning airports, VORs, NDBs, intersections, SID/
STARs, and outer markers located throughout the world. Waypoints are stored in the database
by their ICAO identifiers. The ICAO identifiers are taken directly from Jeppesen-Sanderson or government aeronautical charts. This data allows the pilot to create flight plans with minimum effort.
The KLN 94 can also store non-precision approaches. This allows the pilot to select an approach
as a whole, rather than entering the approach waypoint by waypoint.
Information in the database is updated on a perpetual basis. The KLN 94 is designed so that the
user may easily remove the old database and install a current database. The database is housed
in a data card which plugs into the front of the KLN 94. The database can also be updated by loading the information with a personal computer via RS-232 serial interface.
For more information on the availability and cost of updating the database of the KLN 94, refer to
the KLN 94 Pilot’s Guide, P/N 006-18207-0000.
A color liquid crystal display (LCD) is used to display the navigation information. Connections to
the unit are made through one 37 pin and one 25 pin D-sub connector and one BNC coaxial connector all located at the rear of the unit. Also, a phone jack is located on the front panel.

DETAILED CIRCUIT THEORY
POWER BOARD
General
Refer to Figure 4-2 and Power Board section of the Illustrated Parts List as an aid for the following
discussion. The KLN 94 power supply produces the +5.0V, +9V, -12V, +13V, -15V, and +20V
(V_LCD_DRIVE) DC voltages. The power supply configuration enables the KLN 94 to operate on
any input voltage from +9.0VDC (a minimum of +10.0VDC for start-up) to +33VDC with no modification or rewiring. Also, the unit power consumption is virtually independent of the input voltage.
Current flowing through the primary windings of the power transformer T6001 is alternately
switched, on then off, by Q6016. When the primary current is turned on, energy is stored in the
transformer’s magnetic field. When the primary current is turned off, the current flowing in the secondary windings dissipates the stored energy. Five taps on the secondary winding of T6001 are
then rectified and filtered to produce the voltages necessary for operation of the KLN 94. The KLN
94 Power Board provides the required DC supply voltages for all circuitry within the unit.
4.3.1.2
Power Supply Circuitry
4.3.1.2.1
Power Input
Power input to the KLN 94 (11-33_VDC_A_C_POWER) is supplied to pin 19 of J942 on the MAIN
Board. On the MAIN Board, the input power is RF bypassed by a 1000pF and a 1uF capacitor.
The unit is protected from overvoltage damage by an 85V transorb. The input power then passes
through a filter consisting of a 2.5 turn coil, a .01uF and a 1uF capacitor through a 15uH inductor,
and a .1uF capacitor. Then power is passed to the Power Board via pins 30, 31 and 32 of J5006.
On the Power Board, input power is supplied to the +33VDC Overvoltage Shutdown circuit.
4.3.1.2.2
Overvoltage Shutdown Circuit
This circuit senses the input voltage and turns on Q6014 if the input voltage rises above a nominal
voltage of +36VDC. At input voltages less than this, the voltage is low enough to keep zener diode
CR6014 out of conduction.
In the normal condition, no current flows through R6045 keeping the base-emitter junction of
Q6014 at 0V. This will keep Q6014 turned off allowing the gate-source voltage of Q6015 to be
negative (the gate-source voltage of Q6015 is clamped at a maximum of -9.1V by CR3015) and
Q6015 is turned on for normal operation.
If the input voltage increases to a level above the sum of the zener voltage of CR6014 and the
forward drop of CR6013, current flows through R6045. This establishes a negative base-emitter
voltage that turns on Q6014 which clamps the gate-source voltage of Q6015 at -0.2V turning it off.
When Q6015 is off, input power is disconnected. All of the components connected to the output
of this circuit are thus protected from any voltage exceeding +36VDC.
The Overvoltage Shutdown circuit output to the superflags and annunciators, (PROT_AC_PWR),
is routed back to the Main Board through a filter consisting of L6002, C6029, and C6056 while the
input power for all power supply circuitry is routed to the Input Hash Filter.
4.3.1.2.3
Input Hash Filter
The Input Hash Filter is a pi filter consisting of L6003, C6015, C6016, C6022, and C6026. The
filter reduces ripple on the input power line and protects the power supply circuitry from any externally induced ripple voltage. The hash filter output is routed to the input power steering diode
CR6016. CR6016 couples either the Input Hash Filter circuit output or the Backup Capacitor circuit output to the Low-Voltage (LV) Flyback Transformer (XFMR_HI) and to the front panel On/Off
switch (PWR_SW_HI).

Page 4-21
BENDIX/KING
4.3.1.2.4
KLN 94
ON/OFF Control
The On/Off Control circuit monitors the signal from the front panel On/Off switch (PWR_SW_LO),
the avionics power bus (AIRCRAFT_POWER_MONITOR), and the microprocessor-controlled
shutdown line (POWER_SHUTDOWNn). If these inputs allow the unit to turn on, the On/Off Control circuit outputs an active-low ENABLEn signal. When the ENABLEn signal is low, the LV On/
Off Switch circuit allows the LVPS to start up. Q6028 and Q6030 bring the ENABLEn line to the
low state when both are on. Q6028 is turned on when the front panel On/Off switch is pushed in
to the ON position, connecting PWR_SW_LO to PWR_SW_HI. While in normal operation, Q6030
is held on by the presence of +5V through R6096 and CR6038.
However, during initial startup, Q6030 can only be turned on by the presence of at least +6VDC
on the AIRCRAFT_POWER_MONITOR line, or by C6058 being charged through R6080 and
CR6037 while Q6028 is off (front panel On/Off switch pulled out to the off position). Under this
condition, Q6030 is held on by C6058 long enough for the LVPS to start once Q6028 turns on
(front panel On/Off switch pushed in to the ON position). The circuit operates this way to allow the
unit to restart (if the KLN 94 is connected to an external emergency battery supply) by cycling the
On/Off switch after the avionics power bus drops out and the unit has been shut down due to a
POWER_SHUTDOWNn being asserted.
A POWER_SHUTDOWNn can be asserted by the KLN 94 Host microprocessor when the KLN 94
is connected to an external emergency battery supply and the AIRCRAFT_POWER_MONITOR
line indicates a loss of avionics bus power. This is done to conserve battery supply life. A low
level on the POWER_SHUTDOWN line causes R6079 to conduct base current from Q6023, turning it on. This causes C6057 to rapidly charge through R6098, turning on Q6029. When Q6029
turns on, it pulls the gate of Q6030 low through R6095, turning off Q6030. As the LVPS shuts
down and +5V falls to 0V, C6057 slowly discharges through R6099 keeping Q6029 on long
enough for the unit to remain shut off.
4.3.1.3
4.3.1.3.1
LVPS Circuitry
LV Controller/Switcher
The Low-Voltage Power Supply (LVPS) generates the required unit DC power outputs. This power supply is a Flyback topology using a dedicated current-mode control pulse width modulator
(PWM) integrated circuit (IC) (U6002). The LV Controller/Switcher circuit is made up of this IC and
U6003-B which provides undervoltage shutdown. Power supply voltage to the control circuitry is
provided through CR6028 from the +13V output when the LVPS is running or through CR6029
from the Bootstrap Power Supply during startup.
This voltage is switched by the LV On/Off Switch (Q6018-A) and is applied to U6002 and U6003
only if the ENABLE line from the On/Off Control circuit is low. The PWM IC generates an internal
reference voltage which is accessible at pin 14 (5V_LVPS_REF). The PWM IC operates at 128
kHz as set by R6055 and C6033, and the output at pin 10 drives Q6016 (an N-channel switching
FET) through R6050. During the time that Q6016 is turned on, current is sourced from C6024,
C6025, and C6020 on the XFMR_HI line through the primary windings of the LV Flyback Transformer (T6001) and returned to ground through current sense resistors R6048 and R6049. These
resistors generate a current sense voltage that is filtered by R6051 and C6041 and provided to
U6002 for current-mode regulation.
When Q6016 is turned off, the energy stored in T6001 as magnetic flux causes current to flow in
the secondary windings. This is known as Flyback. Parasitic elements in the transformer also
cause a Flyback voltage spike to occur in the primary of T6001. A snubber network consisting of
C6021, R6047, and CR6019 capture this energy and return it to power input capacitors C6024,
C6025, and C6020. Ferrite inductor L6005 reduces unwanted RF emissions.

15599M00.JA
Rev 0, Sept/2000
BENDIX/KING
KLN 94
Soft start and shutdown control is provided by CR6025 which serves to hold the COMP output (Pin
1) of U6002 low to delay startup or initiate shutdown. Undervoltage shutdown is generated by
U6003-B pulling pin 1 (COMP) of U6002 to ground. This occurs when V_IN falls below 7.2V. If
this happens, R6067 provides hysteresis to prevent restart until INT_AC_PWR has returned to at
least +9.0V.
4.3.1.3.2
Bootstrap Power Supply
The Bootstrap Power Supply provides DC power to the LV Controller/Switcher PWM IC (U6002)
and to the comparator IC (U6003) until +13V can ramp up and supply the power. This supply goes
into operation when the front panel On/Off switch is pushed in to the on position and
PWR_SW_LO is connected to PWR_SW_HI. This causes CR6033 to conduct and clamp at
+6.2VDC and Q6025 to turn on. As Q6025 turns on, the collector current is sourced through
R6086, providing a negative base-emitter voltage for Q6026. This turns on Q6026, applying
XFMR_HI to the anode of CR6029 and on to the LV On/Off Switch. As the XFMR_HI voltage increases, CR6035 goes into conduction applying emitter feedback to Q6025 through R6083. This
feedback tends to turn off Q6025 that in turn tends to turn off Q6026. In this way, the Bootstrap
Power Supply regulates the output voltage applied to the anode of CR6029. The Bootstrap Power
Supply output voltage varies from +9 to +12VDC as XFMR_HI varies from +11 to +33VDC.
4.3.1.3.3
LV ON/OFF Switch
The LV On/Off Switch consists of Q6018A, R6063, and R6065. This switch controls the power
supply voltage to the LVPS PWM IC (U6002) and the comparator IC (U6003). When the ENABLEn line goes low, the Q6018-A gate-source voltage becomes negative and Q6018-A is turned
on, applying power to U6002 and U6003. This allows the LVPS to start up. When the ENABLEn
line goes high, Q6018-A turns off and the LVPS shuts off immediately.
4.3.1.3.4
LV Flyback Transformer
The LV Flyback Transformer has an isolated primary winding and a tapped secondary winding
with taps for +13V, –12V, +20V, -15V, and +5V referenced to grounded center taps.
4.3.1.3.5
Lowpass Filters
A Lowpass Filter (L6004 and C6046) reduces output ripple on the +13V output of the LVPS. A
second Lowpass Filter (L6006 and C6018) reduces output ripple on the
DISPLAY_LED_DRIVE_HI output of the LVPS. A third Lowpass Filter (L6007, C6038, and
C6036) reduces output ripple on the -12V output of the LVPS. A fourth Lowpass Filter (L6009,
C6030, and C6063) reduces output ripple on the +5V output of the LVPS. A sixth Lowpass Filter
(L6008 and C6045) reduces output ripple on the RF+5 output of the LVPS.
4.3.1.3.6
Power Interrupt Circuitry
The power interrupt circuitry allows the KLN 94 to operate without interruption for at least one second without 11-33_VDC_A_C_POWER. During this one-second interval, the PROT_AC_PWR
output is not backed up, so the superflags will not operate during a power interruption.
4.3.1.3.7
Capacitor Backup
The one-second backup power supply is made up of five 10 Farad, 2.5VDC double layer capacitors in series (C6001, C6006, C6011, C6014, and C6017). Resistors (R6003, R6011, R6027,
R6034, and R6041) equalize charging voltage distribution and bleed off capacitor charge during
unit storage. The Capacitor Backup circuit supplies +8 to +11.0VDC at ~2A-peak current for at
least one second for temperatures down to -20 degrees C. CR6006 helps to prevent over charging.

Power Interrupt Switch
The Power Interrupt Switch provides the control logic and power switches to turn on the Capacitor
Backup circuit during power interrupt. U6003-A senses the output voltage from the Input Hash
Filter and compares it to a reference voltage that is generated by U6002 pin 14 (5V_LVPS_REF).
R6060 provides about 0.7V of hysteresis. Since U6003-A is powered by the Bootstrap Power
Supply, the output is low at unit power-up. Under this condition, the output remains low until V_IN
drops to about +10.1VDC. At this voltage, the output of U6003-A goes high and cannot return low
until the input voltage returns to about +10.8VDC. When the output of U6003-A goes high,
CR6009 and CR6026 stop conducting. This causes Q6021 to turn on, sinking current from the
Capacitor Backup circuit through R6033 and R6040. The resulting negative gate-source voltage
on Q6012 turns it on, connecting the Capacitor Backup circuit to the input power steering diode
CR6016. CR6016 couples the Backup Power Supply circuit output to the Low-Voltage (LV) Flyback Transformer (XFMR_HI) and to the front panel On/Off switch (PWR_SW_HI). This also
shuts down the Capacitor Charger circuit through CR6009.
4.3.1.3.9
Capacitor Charger
When FDBK_13V is present, this circuit charges the Capacitor Backup circuit through R6014,
R6015, Q6018-B, and CR6007. The Capacitor Backup circuit is sufficiently charged at +10.5VDC
to sustain a one-second interrupt. The Capacitor Charger circuit will take approximately 3 minutes
to recharge the Capacitor Backup circuit to +10.5VDC after a power interruption and approximately 6 minutes to charge up to this voltage on initial power-up.
4.3.1.3.10
Button Backlighting Supply Circuitry
The Button Backlighting Supply generates the required unit DC power for the front panel nomenclature and buttons. This power supply is a simple switcher using a dedicated current-mode control pulse width modulator (PWM) integrated circuit (IC) (U6001).
Power supply voltage to the Button Backlighting control circuitry is provided through CR6005 from
the +13V output when the LVPS is running. Power is provided through Q6001 from the
FILT_AC_PWR filter whenever the unit is shut down. Voltage FDBK_13V is applied to U6001
through CR6005 only if the ENABLEn line from the On/Off Control circuit is low.
The PWM IC generates an internal reference voltage that is accessible at pin 14. The PWM IC
operates at 128 kHz as set by R6010 and C6010. Output pin 10 drives Q6008 (an N-channel
switching FET) through R6008 and R6022. During the time that Q6008 is turned off, current is
sourced to C6007 which is fed back to U6001 to maintain a constant voltage (approximately
12.5VDC). R6023 and R6025 divide the fed back sense voltage for U6001 to maintain a 2.5-volt
reference at pin 3 of U6001.
Charging current for L6001 is delivered through Q6002 during those portions of the PWM cycle
when Q6006 is turned on. Resistor dividers R6002 and R6006 work with CR6004 to make sure
Q6002 is properly turned on and that Q6002’s gate-source voltage limit is not exceeded. When
Q6008 is turned off, the energy stored in L6001 as magnetic flux causes current to flow in CR6010
to C6007. Q6006 shuts off the incoming current during those portions of the PWM cycle when
L6001 is delivering its stored energy. During this time, CR6002 conducts and provides a ground
for the negative-going end of L6001.
The button backlighting requires two different current levels, one for normal operation, and one for
the situation where the unit’s aircraft power is on but the unit is turned off. Q6009-B is the pass
transistor providing these current levels. Resistors R6038 and R6039 apply gate-source voltage
to Q6009-B to turn it on.
During normal operation, current flows from CR6010 through Q6009-A and current limit resistors
R6028 and R6030, as well as current limit resistor R6029. This current then flows through Q6009B and on to the front panel via J6005-15.
Page 4-24
15599M00.JA
Rev 0, Sept/2000
BENDIX/KING
KLN 94
If too much current flows, R6037 will begin to turn on Q6011 which then cuts back gate drive to
Q6009-B, thereby limiting the current.
When the unit is turned off, the +5V power applied to the gate of Q6010 will be so low that Q6010
will be off. This causes R6036 and R6035 to set the gate-source voltage of Q6009-A at such a
small magnitude that R6028 and R6030 no longer provide current. Only R6029 provides current
which is just enough to provide dimly lit buttons. CR6011, C6013, and R6032 make up a timing
network to make sure on/off transitions are handled smoothly, eliminating flashes of light.
Resistor R6031 provides a load to make measurements easier during troubleshooting. Bypass
capacitors C6012 and C6052 reduce noise. R6020 is a current sense resistor that generates a
current sense voltage that is filtered by R6026 and C6009 and provided to U6001 for current-mode
regulation.
4.3.1.3.11
Display Backlighting Supply
The LEDs of the display assembly’s backlighting must be supplied with a stable current source to
regulate brightness and heat generation. Q6022 is the pass transistor providing this current
source. Resistors R6088 and R6089 apply gate-source voltage to Q6022 to turn it on.
During the portion of the PWM cycle when the LEDs are conducting, current flows from L6006
through current limit resistors R6093, R6092, R6091, and R6090. This current then flows through
Q6022 and on to the front panel via J6005-6. If too much current flows, R6087 will begin to turn
on Q6027, which then cuts back gate drive to Q6022, thereby limiting the current.
Resistor R6069 provides a load to make measurements easier during troubleshooting. Bypass
capacitors C6043 and C6048 reduce noise.
4.3.1.3.12
+9V and -15V Voltage Regulators
Two regulators provide Zener diode controlled voltages. In the +9V regulator, the base voltage
(and therefore the emitter voltage) of Q6013 is limited by the voltage rating of CR6012. Resistor
R6042 provides base drive current as well as Zener current. Bypass capacitor C6044 reduces
high frequency noise. In the -15 regulator, the base voltage (and therefore the emitter voltage) of
Q6024 is limited by the voltage rating of CR6030. Resistor R6081 provides base drive current as
well as Zener current. Bypass capacitor C6049 reduces high frequency noise.
4.3.1.3.13
LCD Bias Supply and Timing Control
The supply for the display assembly’s LCD bias voltage is derived from the voltage supplied by
rectifier CR6023. First, the voltage is regulated. Then, a timing control makes sure that the LCD
bias is applied to the display only when +5V is present. This prevents damage to the LCD display.
The voltage present on CR6023’s cathode is applied to the nominal +20.5V regulator consisting
of Q6019, R6056, CR6022, and CR6021. This regulator is very similar to that used in the +9V
regulator described elsewhere.
Under normal conditions, the reset controller’s output pin, U6004-1, applies base drive to Q6017,
causing it to be turned on fully. This causes resistors R6058 and R6059 to apply base drive to
pass transistor Q6020. In this condition, Q6020 is fully on, and the V_LCD_DRIVE signal on
Q6020’s collector is essentially the same as the voltage present on regulator Q6019’s output. Bypass capacitors C6050 reduces noise.
During power up, the reset controller’s output pin, U6004-1, stays low for a short period of time
after a valid +5V supply level is detected. While it is low, Q6017 doesn’t conduct which causes
Q6020 to also be turned off. Resistor R6057 keeps the level of the LCD Bias Supply at 0V while
the +5V supply voltage rises to normal levels. When the time period is complete, the timing control
assumes normal operation as described above.
Rev 0, Sept/2000
15599M00.JA
Page 4-25
BENDIX/KING
KLN 94
At power down, the reset controller’s output pin, U6004-1, goes low immediately after a dip in the
+5V supply is detected. When it goes low, Q6017 stops conducting which causes Q6020 to stop
conducting. Resistor R6057 bleeds down the level of the LCD Bias Supply at least as quickly as
the +5V supply voltage falls.
4.3.1.3.14
Fan Control
Level shifter transistors Q6005 and Q6008-A permit the standard 5V logic of the Host microprocessor to control the internal blower fan using the -12V supply. Resistors R6071, R6007, and
R6005 supply the needed bias currents. Transistor Q6007 is driven via base drive resistor R6018
in the event that current sense resistor R6019 detects overcurrent conditions during fan turn on.
When Q6007 turns on, the gate source drive across Q6008-A is reduced, thereby limiting fan current. C6042 reduces noise.

FRONT PANEL MODULE ASSEMBLY
The Front Panel Module Assembly consists of Front Panel Assembly, Switch Board Asembly, and
a Display Assembly which houses a Backlight Board and a Controller Board. Refer to Figure 4-3
and applicable sections of the Illustrated Parts List as an aid for the following discussion.
4.3.2.1
FRONT PANEL ASSEMBLY
The Front Panel Assembly consist of a Button Board, a light block, and a switch membrane.
4.3.2.1.1
BUTTON BOARD
Nine pushbutton and 3 dome switches are routed through J1017 and J1007 to the Switch Board.
When any button is depressed, the signal is pulled to a ground (low) state. Button backlighting for
the KLN 94 is provided by 18 amber colored LEDs which are powered by PWM signal from the
Main Board based on the 28V/14V lighting bus levels. This feature only requires one version of
the unit to accommodate both lighting schemes.
4.3.2.1.2
SWITCH BOARD
Power switch U7005, when pushed to the ”ON” position, pulls connector pin P7005-67 to the same
potential as connector pin P7005-66. This enables the power supply. The Variable Resistor within
U7005 controls the voltage of the wiper when turned. This voltage is fed to the Host microprocessor to vary the pulse width modulation of the Backlight LEDs which varies the intensity of the
LCD Display.
The twelve switch signals from the Button Board, the Scan switch, as well as switches U7001
through U7004 (photo interrupters used for the increment/decrement knob functions) are converted to a 24 bit serial data stream by U7007 and U7008. This serial data is fed to the CPU Card to
be polled by the Host microprocessor.

This assembly contains a color LCD display, display drivers, a display controller chip, and an LED
Backlight Board. The Backlight Board contains 147 (21 banks of 7) LEDs. These are pulse width
modulated by the Main Board with an approximate 21VDC signal. The display assembly is communicated with through the Switch Board by the Main Board’s graphics microprocessor.

General
Refer to Figures 4-1(overall block diagram), 4-4 (Host microprocessor diagram), 4-5 (Graphics microprocessor diagram), and 4-6 (input/output diagram) and applicable sections of the Illustrated
Parts List as an aid for the following discussion. The Main Board has two microprocessors: the
Host and the Graphics. The Host microprocessor controls all I/O functions of the rear panel connectors as well as the internal communication to the GPS engine and the local NAV Database with
all calculation for flight. It also handles the front panel button and knob interface. The Graphics
microprocessor controls the Display module and formats all data to the display as well as all interfacing to the Compact Flash data card. The two microporcessors communicate to each other via
a 2 kiloByte Dual Port Static Ram.
4.3.4.2
Main Board Circuitry
4.3.4.2.1
Real Time Clock
The real time clock circuit consists of Y5002 and U5034. It is configured in the battery backup
mode which means it has power applied at all times regardless if the unit is powered on or not.
Communication with the real time clock and the Host microprocessor is accomplished through a
serial peripheral interface consisting of SCLK and a discrete I/O pin of the Host microprocessor.
4.3.4.2.2
Host Microprocessor
The Host microprocessor, U5031, a Motorola MC68HC16Z1, is a high-speed 16 bit microcontroller which incorporates the following: a 16 bit central processing unit (CPU), system integration
module (SIM), an 8/10-bit analog-to-digital converter (ADC) depicted on table 4-2, a queued serial
module (QSM), general purpose timer (GPT), and a 1024-byte standby RAM (SRAM), interconnected by the inter-module bus (IMB). The system clock is software programmed to 20.972MHz.
A 32.768kHz crystal, part of the reference oscillator, is connected across pin 78 and pin 80.
An internal phase-locked loop (PLL) circuit synthesizes the clock signal from the reference oscillator. Design hardware and software configuration supports changes in clock rate during operation. Because the Host microprocessor is a fully static design, register and memory contents are
not affected by clock rate changes.
4.3.4.2.3
Host Reset Circuit
The Host microprocessor releases the reset line MAIN_HW_RESETn (pin 94 of U5031) only when
the system clock is established and when the external reset line has been released by the external
reset circuit. When locked, the system clock at pin 87 of U5031 should be 8.38MHz immediately
after reset. When powered up, the reset line will only be released when +5V supply is stable.

4.3.4.2.4
Host Flash Memories
The 8Mbit (512k x 16) flash memory (U5010) has a 16 kbyte boot block. This Boot Block is to
ensure that the Boot Software is blocked from any accidental write cycles. For read operations,
MAIN_8M_BOOT_CSn is low, MAIN_RDn is low, and MAIN_WRn is high because of decoding
logic of U5029 and U5041.
During program and erasure, a BDM adapter is connected to J5100. A VPP of +5VDC will be supplied to the Flash VPP when HW_PGM_EN is pulled high by the U5029 PLD. Aternatively, both
the Enter and Cursor keys can be depressed and Program code can be loaded via the Data Loader RS-232 interface. Memory contents of U5010 can then be altered.
4.3.4.2.5
Host Non-Volatile Memory
The Host side of MAIN Board contains one 512kbyte (512k x 8) of non-volatile RAM. The nonvolatile RAM U5024 retains its data by applying the battery voltage (VCC_BAT) connected to pin
32 through U5002 pin 2. This will also hold MAIN_SRAM_CSn high to avoid any spurious chip
selects in the power down cycle when the unit is turned off. When powered on, +5V will provide
the required supply voltage to the RAM through U5002. MAIN_SRAM_CS_INn at pin 13 of U5002
controls MAIN_SRAM_CSn.
4.3.4.2.6
Database Interface
The maximum capacity of the Database Flash Memory Chip (U5009) is 4MBytes and is divided
into banks of 64kbyte. To select each of the banks, 6 bank select lines BS(5:0) are decoded with
U5023 using DISCRETE_CS2n, MAIN_DATA_BUS(15:0) and MAIN_WRn.
The MAIN_DB_CSn is used to enable each 64K bank. To support bank crossover, another chip
select line, DBXOVER_CSn (CS2*), is used to address the 2K memory segment following a given
bank. A 6-bit adder in the U5023 PLD implements the crossover. Note that the adding occurs
without any extra programming since the microprocessor’s CS2* chip select will automatically activate once the 64kbyte address is exceeded.

KLN 94
Graphics Microprocessor
The Graphics microprocessor handles two main functions within the KLN 94. The first function is
the interface to the LCD display. The majority of the data shown on the display is generated from
the Host Microprocessor and passed to the Graphics microprocessor via the Dual Port SRAM
(U5008). The Graphics microprocessor formats this data and presents it to the Graphics Controller chip within the LCD display module.
The second function is the interface to/from the Compact Flash Memory Card. This card holds all
of the NAV Database, as well as, the Terrain Database. When required, the NAV Database is
passed to the Host microprocessor for updating via the Dual Port Ram (U5008). The Terrain Database stays local to the Compact Flash Memory Card and is accessed as needed by the Graphics microprocessor when displaying the "Moving Map" screen.
The Graphics microprocessor (U5030) is an Intel 80386EX. The system clock is 32MHz and can
be monitored on U5030 pin 112. A 64MHz crystal clock (Y5001) is the reference clock.
The Graphics microprocessor can be placed into the reset state by either of two conditions. The
Graphics microprocessor receives a reset, high true, from the signal line GRAPHICS_RESET into
pin 119. This signal is an output of U5029 pin 14. Two conditions can cause this reset.
1) The reset controller chip (U5002) detects that VCC has fallen below or has not risen to an acceptable limit. It then asserts the MAIN_RESETn signal that is decoded in U5029 and asserts
GRAPHICS_RESET.
2) Duart (U5042), which is controlled by the Host microprocessor, can force an assertion of the
DISPLAY_RST signal (pin 14) which is decoded in U5029 and asserts GRAPHICS_RESET.
Upon the release of Graphics Reset, the Graphics microprocessor starts addressing code space
data from the programmed flash part (U5017) starting with all address lines high as the first address. The memory map of the Graphics Microprocessor is depicted in the following table.

VPP and Compact Flash VCC
Normal operation for the Flash memory devices occurs when the VPP signal of U5003 pin 13 is
GND. This output is controlled by GRAPHICS_RESET and HW_PGM_EN signals. When both
the GRAPHICS_RESET signal and HW_PGM_EN are low, then VPP is grounded and normal
read accesses are done on the Flash memory devices. When HW_PGM_EN is high and
GRAPHICS_RESET is low, then the FLASH memory devices can be written to and programmed.
The Compact Flash VCC (CF_VCC) signal line on pins 16, 14 and 2 supplies the 5 volt power to
the Compact Flash Card and protects the line from over-current transients which may occur if the
card is removed or replaced while the unit is on.
4.3.4.2.9
Graphics Flash Memories
The 8Mbit (512k x 16) flash memory (U5017) has a 16kbyte boot block. The boot block is a special address memory location within the flash device. It has specific addressing/encoding requirements which ensure that the boot block is locked for all normal programming and read operations.
For read operations, GRAPHICS_CODE_CSn is low, PERIPH_RDn is low, and PERIPH_WRn is
held high due to the decoding logic of U5038.

front panel at the time power is applied to the unit. The memory contents of U5017 can then be

The Graphics microprocessor utilizes four 512kbyte (512k x 8) SRAM devices. One of these volatile SRAMs (U5001, U5006, U5018, or U5025) can be read or written to by the microprocessor
when either GRAPHICS_SRAM1_LOn, GRAPHICS_SRAM1_HIn, GRAPHICS_SRAM2_LOn, or
GRAPHICS_SRAM2_HIn is held low while the other three are high. PERIPH_RDn is held low on
a read command and PERIPH_WRn is held low on a write command. These signals are decoded
in U5038 programmable decode logic device.
4.3.4.2.11
Compact Flash Database Interface
The Compact Flash Database Card is manufactured by an external supplier and programmed with
both the NAV and Terrain Databases. The data passed to/from the Compact Flash Database card
through the I/O Board is controlled by U5039 and U5040 as data buffers and latches as well as
U5038 as the controller for these buffers and latches. To read from the Compact Flash Database
card, the microprocessor asserts GRAPHICS_CF_CSn low, GRAPHICS_RDn low,
GRAPHICS_WRn high, and GRAPHICS_ADSn low which are then decoded within U5038. The
decoder generates CF_CE_Hn, CF_CE_Ln, PERIPH_CF_BUF_En, PERIPH_RDn, and
PERIPH_WRn signals to select the area of the Compact Flash Card that is needed to be read.
4.3.4.2.12
4.3.4.2.12.1
Electronically Programmable Logic Devices.
General
Programmable logic provides various support circuits needed by the unit. This logic circuitry primarily supports the interfacing requirements of the Host and Graphics microprocessors. Six individual EPLDs hold the needed circuitry.
The EPLDs use input logic having voltage requirements similar to industry standard TTL logic.
Output drive voltage is similar to TTL logic also.
4.3.4.2.12.2
Graphics EPLD Interface
GRAPH1, GRAPH2, and GRAPH3 use the GRAPHICS_CLKIN 64MHz clock signal from Y6001
for high speed synchronization of signals. GRAPH3 also uses the 32 MHz GRAPHICS_CLKOUT
signal from the Graphics Microprocessor.
The Graphics logic is spread across three EPLDs identified as GRAPH1 (U5040), GRAPH2
(U5039), and GRAPH3 (U5038) on the schematic. Refer to other sections of this document for a
discussion of specific functions assigned to the Graphics EPLDs. The following paragraphs give
an overview of the functions.
4.3.4.2.12.2.1
Buffering and multiplexing of the Graphics microprocessor data bus, PERIPH bus, and CF_BUS.
This function is needed because the disable times for the SRAM, CODE, DPRAM, and CF devices
are longer than the 386EX’s timing spec. Without the buffers, bus contention could occur when a
write cycle follows a read to one of these devices.

Rev 0, Sept/2000
BENDIX/KING
4.3.4.2.12.2.2
KLN 94
Generation of control signals for buffering and multiplexing of the 386EX
data bus, PERIPH_BUS, and CF_BUS.
This avoids PERIPH bus contention with a possible previous PERIPH read operation.
4.3.4.2.12.2.3
Generation of customized RDn and WRn signals for PERIPH_BUS and
CF_BUS accesses.
These customized PERIPH_RDn and PERIPH_WRn signals are generated because the CompactFlash card requires address and chip select hold times of 20ns following RDn or WRn deactivation. Also, the read data from the CompactFlash card must be latched since the 386EX will
not read the data until the end of the cycle.
4.3.4.2.12.2.4
Wait state and GRAPHICS_READYn generation for PERIPH_BUS and
CF_BUS accesses.
The EPLD state machine generates and outputs GRAPHICS_READYn to the 386EX in order to
control the length of a PERIPH or CF bus cycle. Besides controlling the length of the bus cycle,
the state machine also provides the control signals for the generation of GRAPHICS_BUF_ENn,
PERIPH_CF_Buf_ENn, PERIPH_RDn, PERIPH_WRn, and LATCH_EN.
4.3.4.2.12.2.5
Generation of high and low byte chip selects for 386EX SRAM and CF access.
This function generates the high and low byte chips selects for SRAM and CF from the
GRAPHICS_BHEn, GRAPHICS_BLEn, GRAPHICS_SRAM1_CSn, GRAPHICS_SRAM2_CSn,
and GRAPHICS_CF_CSn signals from the 386EX.
Inversions of the DPRAM interrupt signal to the 386EX.
The DPRAM interrupt output is active low. The EPLD simply inverts this signal since the 386EX
requires positive edge triggered interrupts.
4.3.4.2.12.2.6
JTAG Mode timing adjustment.
The JTAG mode for the ’386 microprocessor has bus cycles far slower than normal operation, so
the state machine must be disabled to prevent time-outs. In JTAG mode, the state machine normally controlling critical bus timing is disabled. Instead, PERIPH_WRn and
PERIPH_CF_BUF_ENn will follow GRAPHICS_WRn. GRAPHICS_BUF_ENn and PERIPH_RDn
will follow GRAPHICS_RDn. A JTAG programming/debugging program hosted on a notebook PC
must cause GRAPHICS_CF_CSn, GRAPHICS_CODE_CSn, and GRAPHICS_SRAM1_CSn to
all go low all at the same to enter JTAG mode. Exiting JTAG mode is done by either bringing
MAIN_RESETn low, or by bringing GRAPHICS_CODE_CSn, GRAPHICS_SRAM1_CSn, and
GRAPHICS_DPRAM_CSn low at the same time.
4.3.4.2.12.2.7
REGn Modification.
It was found that the Sandisk Compact Flash cards do not utilize the variable bus timing of the
common memory mode. SanDisk only uses fixed bus timing similar to the attribute mode. In particular, the CF card does not implement WAITn signaling. Fixed wait states must be used. Therefore, REGn has been internally tied low in the EPLD logic to cause the state machine to use fixed
bus timing similar to the attribute mode during CF accesses.

Main EPLD Functionality
The Main logic is spread across three EPLDs identified as MAIN1 (U5029), MAIN2 (U5041), and
MAIN3 (U5023) on the schematic. Refer to other sections of this document for discussion of specific functions assigned to the MAIN EPLDs. The following paragraphs give an overview of the
functions.
4.3.4.2.12.4
Main 1 EPLD Controller
The MAIN1 EPLD controller holds a variety of functions supporting the Host microprocessor.
4.3.4.2.12.4.1
Decoding for the DUART Chip.
Duart Chip enable/Discrete Chip select 3 by decoding the MAIN_DUART_CSn signal from the microprocessor along with MAIN_ADDRESS_BUS4. When both signals are low DUART_CEn is asserted low and when only MAIN_DUART_CSn is low DISCRETE_CS3n is asserted low.
4.3.4.2.12.4.2
Decoding for the NAV Database Chip.
Database Decoder logic decodes the MAIN_DBXOVER_CS and MAIN_DB_CSn chip selects
along with MAIN_WRn signal from the microprocessor. If either MAIN_DB_CSn or
MAIN_DBXOVER_CSn is asserted low then DBASE_LOCAL_CSn is asserted low. In this condition, with MAIN_WRn high, a read access is done to the local Database chip. If MAIN_WRn is
low, data is written to the local Database chip.
4.3.4.2.12.4.3
Lower and upper chip enable decoding of the Flash memory.
This is accomplished by asserting MAIN_ROM_CSn or MAIN_XROM_CSn. With the assertion of
either of these signals low will assert MAIN_8M_BOOT_CSn. When MAIN_XROM_CSn is high
and MAIN_ROM_CSn is low, the MAIN_8M_ADDRESS_A19 signal line for the flash is asserted
low. This is the lower Flash addressing mode.
4.3.4.2.12.4.4
Decoding for the Static RAM Chip.
Both MAIN_SRAM1_CSn and MAIN_SRAM2_CSn are decoded to assert MAIN_SRAM_CS_INn
low. This addressing space is shared with the Database and PERIPH chip selects as well. If either of the Database or the PERIPH chip selects are asserted the MAIN_SRAM_CS_INn signal is
held high regardless of the status of MAIN_SRAM1_CSn or MAIN_SRAM2_CSn.
4.3.4.2.12.4.5
Enabling of the HW_PGM_EN and / or WPn signals.
Decode logic handles the HW_PGM_EN and WPn signals to enable the write capabilities for the
Flash chips. If either the BDM or the JTAG connectors are connected and RESETn is not asserted
low, then WPn and HW_PGM_EN will be high. When both the CURSOR and the ENTER keys
are depressed simultaneously on the front panel when power is applied to the unit, only
HW_PGM_EN will be asserted high and WPn will remain low. This is intended for unit application
code programming only. WPn must be driven high when programming the Boot portion of the
Flash memory devices.
4.3.4.2.12.4.6
Creation of the DISCRETE_CS1n and DISCRETE_CS2n signals.
A 3-to-8 decoder monitors the MAIN_ADDRESS_BUS lines 1 through 3, as well as,
MAIN_DISCRETE_CSn from the microprocessor to generate the DISCRETE_CS1n and
DISCRETE_CS2n signals. The DISCRETE_CS1n signal will be asserted low when all three
MAIN_ADDRESS_BUS signals are low and MAIN_DISCRETE_CSn is low.
Page 4-34
15599M00.JA
Rev 0, Sept/2000
BENDIX/KING
KLN 94
The DISCRETE_CS2n signal will be asserted low when the MAIN_DISCRETE_CSn is low, the
MAIN_ADDRESS_BUS1 is high, and the other two MAIN_ADDRESS_BUS signals are low.
4.3.4.2.12.5
Main 2 EPLD Controller
The MAIN2 EPLD controller holds the Display Video decoding, Audio Tone/Clock Generator, and
some discrete line decoding.
4.3.4.2.12.5.1
Creating of Display Video Controller Control Signals.
All the logic for the specific timing requirements for the Video Controller chip in the display assembly is included here. The logic within this function monitors all read and write accesses to the display assembly. It also decodes the VIDEO_READY from the display assembly, and signals the
Graphics microprocessor when to terminate a write or read cycle by asserting
GRAPHICS_READYn signal line low.
4.3.4.2.12.5.2
Clock Generation.
A divider divides the 32 MHz clock out of the Graphics microprocessor down for the Audio Tone
(1 kHz.) and the PCLK (Approximately 695 kHz.). PCLK is a signal required by the main microprocessor for OBS sine and cosine read synchronization.
4.3.4.2.12.5.3
Read/Write Separator.
This separator is an exclusive-or function to separate the single line R_Wn from the Main Microprocessor into individual RDn and WRn signals needed by various chips.
4.3.4.2.12.5.4
Decoding of Discrete Read Chip selects.
The two Discrete Read Chip selects, DISCRETE_CS1_RDn and DISCRETE_CS2_RDn, are asserted only when the RDn signal is asserted along with the DISCRETE_CSn signal.
4.3.4.2.12.5.5
Buffer for DBASE_VPP_EN.
The DBASE_VPP_EN is buffered from the DBASE_PROG_MODE signal to enable the Local Database Flash VPP line when programming this Flash device.
4.3.4.2.12.5.6
OBS_DRIVE Output.
The OBS DRIVE output is the 450 Hz signal generated by the DUART, but gated by the
OBS_SELECT signal.
4.3.4.2.12.5.7
CompactFlash Presence Logic.
The CF_PRESENT signal is generated from the two Card Detect lines of the Compact Flash Card.
If both CD1n and CD2n are asserted low by having the Compact Flash Card installed the
CF_PRESENT will be asserted high.
4.3.4.2.12.6
Main 3 EPLD Controller
The MAIN3 EPLD controller holds discrete output latches and the adder and latches for the bank
selects.
4.3.4.2.12.6.1
Rev 0, Sept/2000
Discrete Output Latches.
15599M00.JA
Page 4-35
BENDIX/KING
KLN 94
Three 8 bit latches are connected to the microprocessor data bus. An independent
DISCRETE_CSn signal for each latch is controlled by the WRn signal. If WRn is low and the appropriate DISCRETE_CSn signal is low, the data from the DATA_BUS will be latched to the appropriate output pin.
4.3.4.2.12.6.2
Bank Select Generation.
Bank selects signals (BS[5..0]) are latched and used with the the Six-Bit Adder. The Bank Select/
Six Bit Adder handles the appropriate decoding for the NAV Database extended block read feature. This feature is enabled when the DBXOVER_CSn signal is asserted low.
4.3.4.2.13
Dual Port Sram
The Dual Port Sram (U5008) is a 2kByte dual addressable static ram device for inter-microprocessor communications. The Host microprocessor and the Graphics microprocessor communicate
through this device. This allows information, such as display data, to be passed between the Host
and the Graphics microprocessors. Also, database information may be passed from the Compact
Flash Card, through the Graphics microprocessor, to the Host microprocessor.
4.3.4.2.14
Voltage Monitor Circuit
U5020 is an analog multiplexer. Various voltages are scaled and level shifted before entering
U5020. These levels can be monitored on a TEST page of the KLN 94. The internal ADC of the
Host microprocessor samples the PWRBUS signal which is an output of U5020. PBUS #0, PBUS
#1, and PBUS #2, are outputs of U5004 which accomplishes channel selection.
4.3.4.2.15
+5v Precision Reference/Temperature Transducer
A +5VDC reference (5VREF) is provided by U5019 to U5031 pin 72 for the Host microprocessor’s
analog-to-digital (ADC) module. This signal is also used as a reference level for the front panel
backlight intensity level, the OBS sine and cosine filters, and for all annunciator detect comparators. A V_TRIP comparator (U5037) uses 5VREF to provide a current sense trip voltage of -.085
VDC to the annunciator drivers for external short circuit detection. The reference IC (U5019) provides the unit temperature at pin 3. The voltage at this pin (approximately 2.1mV/K) is scaled by
U5011 before being applied to the Host microprocessor ADC where it is read as actual temperature.
4.3.4.2.16
4.3.4.2.16.1
OBS Circuits
OBS Output
The 450Hz signal required to excite the resolver is generated by DUART U5042. The square
wave is converted to a sine wave by a fourth order lowpass filter comprised of U5021-A, U5021B, and related components. The signal is then level shifted and amplified by the output driver
stage consisting of U5021-C, Q5020, Q5035, and related components.
U5021-D and related components form an over-current detector for the output circuit by comparing the collector voltage of Q5020 with the driving signal. OBS OVERLOADn will be active when
output current is more than 70mA.
4.3.4.2.16.2
OBS Inputs
The sine and cosine outputs of the OBS resolver are read back via OBS SIN and OBS COS. Both
input circuits function identically so only operation of the OBS SIN will be described. The input
signal is level shifted and scaled to within +5V by R5062, R5040, R5182, C5069, CR5011 and
U5022-C. It is then filtered by a second order low pass filter consisting of R5183, R5049, C5055,
C5056 and U5022-A.

Rev 0, Sept/2000
BENDIX/KING
KLN 94
CR5015 removes its negative cycle before the internal ADC of the Host microprocessor samples
it. Q5021 and R5180 are used to select the bias of the input signal. The bias is currently set to 0V.
4.3.4.2.17
Dimming Pot control
The DIM_POT_SENSE circuitry consist of a 5VREF signal at one input to the pot. The wiper voltage is monitored by a non-inverting voltage follower op-amp (U5036) and is passed on to the Host
microprocessor to control backlight intensity.
4.3.4.2.18
Lateral and Vertical Deviation Flags
The LATERAL_DEV_FLAG+ signal goes to its nominal 0.7V state when the Lateral Superflag is
in the active high state. The signal goes to its nominal 0V state when the Lateral Superflag is in
its low state. Resistors R5010 and R5148 work with clamp diode CR5004 to create the proper
voltage levels. The VERTICAL_DEV_FLAG+ output works similarly with the signal’s output states
corresponding to those of the Vertical Superflag. Resistor R5015 works with clamp diode CR5021
to create the proper voltage levels.
4.3.4.2.19
Superflag Outputs
The LATERAL_SUPERFLAG output circuit consists mainly of two control lines from U5004, two
diodes (CR5005 and CR5008), an NPN transistor (Q5019), a protection diode (CR5007), and a
drive FET (Q5012) which is turned on when the LATERAL_DEV_FLAG+ is on. To turn on the
LATERAL_DEV_FLAG+, a high is written to either pin 3 or 4 of U5004 which enables Q5019 to
drive Q5012. R5004 provides a load for Q5012 when the LATERAL_SUPERFLAG is not loaded.
CR5007 limits the maximum gate voltage of Q5012 to approximately 6.2VDC. R5161 provides a
feedback output status for the Host microprocessor via U5005. EMI and lightning protection for
the line is provided by the suppressor card and C5129. Operation of the
VERTICAL_SUPERFLAG circuit is functionally identical to the LATERAL_SUPERFLAG except
that only one control signal is required. This is pin 2 of U5004. STEERING_SUPERFLAG is identical to VERTICAL_SUPERFLAG but is driven by U5013-7.
4.3.4.2.20
+From Outputs
The +FROM flag circuit consists of U5036-D and two control lines from U5004. When the TO_EN
signal line is greater than the FROM_EN line, the +FROM output will be at a negative potential
indicating a "TO" direction. When the FROM_EN is greater than the TO_EN signal line, the
+FROM output will be at a positive potential indicating a "FROM" direction. Either of these signals
when driven high will activate the Lateral Superflag circuitry. When both the TO_EN and the
FROM_EN signals are low, the LATERAL_DEV_FLAG+ will be low. This effectively puts the
+FROM signal at the same voltage level as the +TO output of the KLN 94. EMI protection for this
line is provided by C5207.
4.3.4.2.21
Deviation Outputs
Two deviation outputs are available on the KLN 94: Lateral Deviation and Vertical Deviation. The
operation of each output is functionally identical. U5037-C acts as a filter and level shifter to convert the L_CDI PWM signal to levels acceptable for use with a lateral deviation meter movement..
4.3.4.2.22
Annunciator Outputs
Discrete output data is sent from the Host microprocessor via the serial peripheral bus and latched
into U5013. This device is a serial to parallel shift register.
The KLN 94 provides eight annunciator outputs. Since all are functionally identical, only the WAYPOINT ANNUNCIATEn line will be described.
When pin 15 of U5013 is high, Q5013-B will be turned on. This will sink current from an external
load. Q5026, R5152, R5017, and R5018 form a current fold-back circuit.
Rev 0, Sept/2000
15599M00.JA
Page 4-37
BENDIX/KING
KLN 94
This limits the sinking current of Q5013-B to approximately 350mA. When pin 15 of U5013 is low,
Q5013-B will be turned off.
4.3.4.2.23
DUART and RS-232 Interface
DUART U5042 provides two asynchronous receiver-transmitters. It is used for serial communication between the Host microprocessor and the GPS PXpress Card Receiver. It is also used for
communication between the Host microprocessor and the data loader RS-232. The communication baud rate is derived from a 3.6864MHz clock oscillator (Y5004). DBTX_INTn interrupts the
Host microprocessor when U5042 is ready to transmit data to the data loader RS-232. When receiving data from the data loader RS-232, DBRX_INTn interrupts the Host microprocessor.
In addition, U5042 is used to read external discrete input signals. U5044 is a discrete input level
converter. U5044 is always enabled and has internal protection for lightning. GLUINTn will interrupt the Host microprocessor if there is a level transition in either one of the pins from IP0 through
IP3, if data is received from the GPS PXpress Receiver Card, or if U5042 is ready to transmit data
to the GPS PXpress Receiver Card.
U5027 and U5026 are level translators that convert RS-232 data from a 5V level to an EIA-232
standard level and vice-versa. Capacitors on the input and output lines are used for EMI suppression.
4.3.4.2.24
GPS Displayed Discrete input.
The GPS_DISPLAYED input pin is EMI suppressed by C5212; level shifted by CR5020, R5129,
R5128, and R5127; and passed on to U5042 to be monitored by the Host microprocessor.
4.3.4.2.25
Serial Peripheral Interface
The front panel knobs and buttons, real time clock, discrete inputs, and discrete outputs are interfaced to the Host microprocessor via a serial peripheral interface. U5028 is the serial bus address
decoder. The chip select truth table is shown below.

Altitude Audio Alert Driver
U5041 divides the 32MHz clock down to a 1kHz square wave oscillator. Q5023 buffers the
AUDIO_TONE signal. Digital Pot U5045-C controls the amplitude of the signal applied to buffer
U5043-A. The signal is then a/c coupled, scaled, and partially filtered by buffer U5043-B and associated components.

BENDIX/KING
KLN 94
U5043-C and U5043-D are connected to the external lighting bus signals LIGHTING_28V_LO and
LIGHTING_14V. The inverting summing amplifier U5043-D uses R5201, R5122, and R5107 to
scale the voltage. U5043-C filters and inverts the DC voltage level so the Host microprocessor
can use this voltage to control the intensity of the button and nomenclature backlighting LEDs.
4.3.4.2.28
DC Roll Steering Control.
The Host microprocessor controls digital pot U5045-A at a voltage level between +5Vdc and
ground. This level is scaled, level shifted, and filtered by U5037-B, C5161, C5171, R5114, R5115,
R5113, and R5116. Series resistors R5126 and R5125 eliminate unwanted oscillation and increase RF immunity. Capacitor C5179 reduces noise.
4.3.4.2.29
Contrast Control
When DISPLAY_RST is low, the Host microprocessor controls digital pot U5045-D at a voltage
level between +5Vdc and ground. R5123 and C5173 filter the signal. It is then buffered and driven to the display module as CONTRAST adjust by voltage follower U5036-A.
4.3.4.2.30
Hardware Reset Circuit
When the KLN 94 is powered up, the MAIN_RESET signal lines will only be released when the
+5V supply is stable. After U5002 senses a stable +5V, the MAIN_SRAM_CS_INn is passed
through to MAIN_SRAM_CSn signal along with applying +5V to VCC_BAT. The battery voltage
at pin 1 of U5002 will be present at pins 2 and 12 only when +5V at pin 3 is below 4.75 Vdc. The
PFO output of U5002 will indicate to the Host microprocessor the status of the battery. Q5034
inverts the MAIN_RESET signal along with making an open collector signal which allows other devices to drive the MAIN_HW_RESETn signal line.
4.3.4.2.31
Battery Measurement
The voltage of the internal battery at E3 is routed through the voltage follower U5036-B, to be measured by the ADC module of the Host microprocessor U5031.
4.3.4.2.32
Button LED Drive Lo Switch
The active low drive signal for the front panel button backlighting is controlled by transistors
Q5002-A and Q5002-B depending on whether the unit is in the normal operational mode or is
turned off.
In the normal operational mode, reset clamp transistor Q5009 is open. This permits the Host microprocessor’s PWM drive signal, BUTTON_LED_PWM, to be buffered by drive transistors
Q5001 and Q5006. Resistors R5142, R5134, R5137, and R5005 dampen high current noise transients. The buffered PWM signal drives the gate of Q5002-A, which causes the button backlighting LEDs to turn on during that portion of the PWM cycle when Q5002-A is active. Note that since
+5V is active, clamp transistor Q5010 is kept on via R5143, thus preventing Q5002-B to interfere
with the PWM-based control of Q5002-A.
When the unit is turned off, the aircraft bus voltage applied via the PROT_AC_PWR line drive the
gate of Q5002-B via resistor divider R5008 and R5144. Since the +5V supply is off, clamp transistor Q5010 shall be kept off, permitting Q5002-B to stay on. This causes the button backlighting
LEDs to be on.
The timing circuit consisting of R5143, CR5002, and C5005 prevents unwanted bursts of light during transitions of the unit between the normal operation and off states.
4.3.4.2.33
Display Backlighting LED Drive Lo Switch
The active low drive signal for the LED backlight within the LCD display is controlled by transistors
Q5004-A and 5004-B which are paralleled for lower on resistance.

KLN 94
Level shifter transistors Q5008 and Q5011 permit the standard 5V logic of the Host microprocessor to connect the drive transistors to the -12V supply rail during the active low state. Resistors
R5136, R5140, R5006, R5141, R5145, R5147 and R5146 supply the needed bias currents.
Clamp transistor Q5005 is turned on by the GRAPHICS_RESET signal to prevent bursts of light
during that period of start-up when the microprocessor is not initialized.
Driver transistors Q5003 and Q5007 buffer PWM drive signal DISPLAY_LED_PWM. Resistors
R5009, R5135, R5138, and R5139 dampen high current noise transients. The buffered PWM signal drives the gates of Q5004 which causes the display backlighting LEDs to turn on during that
portion of the PWM cycle when Q5004 is active.
4.3.4.2.34
Discrete Inputs
U5015 and U5005 are parallel-to-serial shift registers which are daisy chained together. Discrete
Main Board signals and flags are sent to the Host microprocessor via a serial peripheral bus. They
are read in using SCLK while the DISCRETE_IN_SELECTn is signal held low.
4.3.4.2.35
Gillham Altitude Inputs
The KLN 94 has the capacity for ten Gillham Altitude Inputs, as well as, other discrete inputs. As
these circuits are functionally identical, only the operation of the Gillham Input D4 will be discussed. U5035 translates the input voltage to a digital logic level which is applied to the Main microprocessor data bus when DISCRETE_CS2_RDn is asserted low. C5232 is used for EMI protection.
4.3.4.2.36
Configuration Module
The Configuration Module contains an EEPROM which stores some of the system configuration
information for the KLN 94. The Module is housed in the mounting rack for the KLN 94 and contains a 256-bit EEPROM (U7001) which is communicated to in a serial manner. Signals
EXT_EEPROM, EXT_EEPRM_CS, Serial_OUT_OBI_DATAn, Serial_IN and Serial_CLK run
through the J5006 connector to the Power Board to J943.
4.3.4.2.37
OBI Serial Bus Driver
The OBI_DATA, OBI_CLOCK, and OBI_SYNC signals are created using the latched outputs of
U5023. As all three are identical, only the OBI_DATA circuit will be described here. Driver FET
Q5038 is driven via R5046. When the gate of Q5038 is driven high, the drain pin will be pulled
near 0V. Current limit resistor R5053 and clamp diode CR5014 provide lightning protection.
When a high voltage pulse appears on Q5038’s drain, CR5014 clamps the gate-source voltage.
This causes Q5038 to momentarily shut off, preventing damage.

Final Adjustment
With the contrast value highlighted, turn the right inner knob clockwise until the highlighted contrast value is near the high end of the range, but the text is still readable.
Next, lower the contrast value while observing the color of the white text. As the contrast value is decreased, a transition point must be reached where the white text loses its yellowish tint and becomes bluish-white. When that point is reached, turn the
knob back clockwise so that the contrast value is 15 units greater than at the transition point, thereby causing a slight yellowish tint to return to the white text. This indicates the point of best contrast.
The contrast value must now read within the range of 20 to 235. If it is outside this
range, follow the instructions in Paragraph D. of this procedure. If within this range,
depress the ENT button to store the calibration offset in the unit’s non-volatile ram.

REPAIR
A.
B.
General
This section contains information required to perform limited repairs on the KLN 94
unit. The repair or replacement of damaged parts in airborne electronic equipment
usually involves standard service techniques. In most cases, examination of drawings and equipment reveals several approaches to perform a repair. However, certain repairs demand following an exact repair sequence to ensure proper operation
of the equipment. After correcting a malfunction in any section of the unit, it is recommended that a repetition of the functional test of the unit be performed.
Repair Precautions
1.
Ensure that all ESDS and MOS handling precautions are followed.
2.
Perform repairs and replace components with power disconnected from equipment.
3.
Use a conductive table top for repairs and connect table to
ground conductors of 60Hz and 400Hz power lines.
4.
Replace connectors, coaxial cables, shield conductors, and
twisted pairs only with identical items.
5.
Reference “component side” of a printed circuit board in this
manual means the side on which components are located;
“solder side” refers to the other side. The standard references are as follows: nearside is the component side; farside is
the solder side; on surface mount boards with components
on both sides, the nearside is the side that has the J####
and P#### connector numbers.

MOS Device Protection
MOS (Metal Oxide Semiconductor) devices are used in this equipment. While the
attributes of MOS type devices are many, characteristics make them susceptible
to damage by electrostatic or high voltage charges. Therefore, special precautions
must be taken during repair procedures to prevent damaging the device. The following precautions are recommended for MOS circuits, and are especially important in low humidity or dry conditions.

E.
Store and transport all MOS devices in conductive material
so that all exposed leads are shorted together. Do not insert
MOS devices into conventional plastic “snow” or plastic
trays used for storing and transporting standard semiconductor devices.
Ground working surfaces on workbench to protect the MOS
devices.
Wear cotton gloves or a conductive wrist strap in series with
a 200KΩ resistor connected to ground.
Do not wear nylon clothing while handling MOS devices.
Do not insert or remove MOS devices with power applied.
Check all power supplies to be used for testing MOS devices. and be sure that there are no voltage transients present.
When straightening MOS leads, provide ground straps for
the apparatus for the device.
Ground the soldering iron when soldering a device.
When possible, handle all MOS devices by package or
case, and not by leads. Prior to touching the device, touch
an electrical ground to displace any accumulated static
charge. The package and substrate may be electrically
common. If so, an electrical discharge to the case would
cause the same damage as touching the leads.
Clamping or holding fixtures used during repair should be
grounded, as should the circuit board, during repair.
Devices should be inserted into the printed circuit boards
such that leads on the back side do not contact any material
other than the printed circuit board (in particular, do not use
any plastic foam as a backing).
Devices should be soldered as soon as possible after assembly. All soldering irons must be grounded.
Boards should not be handled in the area around devices,
but rather by board edges.
Assembled boards must not be placed in conventional,
home-type, plastic bags. Paper bags or antistatic bags
should be used.
Before removing devices from conductive portion of the device carrier, make certain conductive portion of carrier is
brought in contact with well grounded table top.
PC Board, Two-Lead Component Removal (Resistors, Capacitors, Diodes, etc.)
1.
Heat one lead from component side of board until solder
flows, and lift one lead from board; repeat for other lead and
